BIODIVERSITA’ DELLE COMUNITA’ BATTERICHE IN UN SUOLO SOTTOPOSTO A BIORISANAMENTO IN MICROCOSMO
2021
Gli idrocarburi (HC) sono uno dei principali inquinanti ambientali. Una tecnologia promettente per il trattamento di siti contaminati si basa sulla biodegradazione degli inquinanti da parte di popolazioni microbiche capaci di utilizzare HC come fonte di carbonio ed energia (Biorisanamento). La necessità di risanare siti contaminati richiede da una parte la caratterizzazione delle comunità microbiche coinvolte nella biodegradazione, dall’altra lo sviluppo di interventi volti a migliorare il potenziale metabolico dei microrganismi degradatori. La nostra attività di ricerca ha avuto come obiettivo quello di caratterizzare e analizzare la biodiversità di comunità microbiche di un suolo contamin…
Forage yield and N2 fixation of Trifolium alexandrinum in pure stand and in mixture with Lolium multiflorum.
2010
The efficiency of grass-legume intercrop systems is affected by various agronomic factors such as crop density, plant spacing and arrangement that may alter the competitive relationships between component crops. This study was aimed to evaluate yield, N concentration, and symbiotic N2 fixation of berseem clover (Trifolium alexandrinum L.) grown in pure stand or in mixture with annual ryegrass (Lolium multiflorum Lam) either in alternating rows or in the same row. The experiment was conducted in two consecutive growing seasons in a semi-arid Mediterranean environment (Sicily, Italy). Dry matter (DM) yields were similar in the mixed stands and in the berseem pure stand; the annual ryegrass pu…
Effects of different boundary conditions and palaeotopographies on the onshore response of tsunamis in a numerical model – A case study from western …
2016
Abstract Hydrodynamic numerical models are essential in modern tsunami hazard assessment. They allow the economical simulation of possible tsunami scenarios for areas at risk and provide reliable and detailed insights into local onshore dynamics. This is especially true when simulations are calibrated with field traces of past tsunami inundation events. Following this approach, the current study focuses on palaeotsunami events indicated by sedimentary and geomorphological field traces in the northern Gulf of Kyparissia (NW Greece). Based on three different digital elevation models (DEM) – reflecting the recent and two palaeotopographies – various tsunami wave constellations according to the…
Frustracje osieroconego dziecka (Jean-Paul Sartre, "Słowa")
2020
In the autobiography, The Words (Les mots 1964), Jean-Paul Sartre analyzes his childhood dominated by his father’s absence and his grandfather’s authority. The sense of being superfluous to the child is difficult to bear but becomes less painful thanks to the writing and the power of language.
